+ | **Title I**: Context-Aware learning models: CALM-Project by José Palma, Juan Botía, University of Murcia | ||
+ | |||
+ | **Abstract**: | ||
+ | In a pandemic scenario, there are a number of technical challenges that need to be addressed in order to be prepared for future pandemics. These challenges relate to the whole life cycle of development. First, since the beginning of a pandemic, it is crucial not only to have reliable sources of data, but also to make this data accessible. In this sense, we need to integrate data from different sources, of different types, most of which have not been collected for modelling purposes, and to monitor the growth of such data with new sources. Second, although the use of predictive models has proved useful, the variable nature of the distributions, | ||
+ | |||
+ | |||
+ | |||
+ | These are the main challenges that CAML project tries to approach. The initial hypothesis of this project is that the development of advanced techniques to detect and characterise concept drift in pandemic scenarios and on different types of data, combining different representation schemes, will not only provide tools to anticipate and react to model degradation, | ||
+ | |||
+ | |||
+ | **Title II**: Concept Drift in Imbalanced Problems by Antonio Guillén-Teruel, | ||
+ | |||
+ | **Abstract**: | ||
+ | We address the challenge of concept drift in imbalanced datasets, which is common in various real-world applications. We build upon the IPIP (Identical Partitions for Imbalance Problems) method, which effectively generates balanced subsets by subsampling the majority class to ensure representation of all minority class instances. This method enhances the performance of ensemble learning models in imbalanced scenarios. | ||
+ | |||
+ | Additionally, | ||
+ | |||
+ | Our work extends these methods to address concept drift, particularly in the context of passive learning. Concept drift occurs when the underlying data distribution changes over time, a phenomenon observed in dynamic datasets like those tracking COVID-19 patient outcomes. We propose adapting the IPIP method to handle concept drift by updating the model with new data chunks over time, ensuring that minority class instances are adequately represented in each update. | ||
+ | |||
+ | Furthermore, | ||
+ | |||
+ | Through extensive experiments on both simulated and real-world datasets, including a COVID-19 patient cohort, we demonstrate the effectiveness of our approach. Our findings suggest that the combination of IPIP and UIC, adapted for concept drift, offers a robust framework for tackling imbalanced data in non-stationary environments. Future work will focus on developing R packages to implement these methods, facilitating their application in various practical settings. | ||
